DETERMINATION OF AGGREGATE CRUSHING VALUE
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS

Table 5.4 presents the statistical data of the LA abrasion mass loss, aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples. As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA. However, this trend is not clear in the case of AIV and ACV.
